Abstract:
According to the observation of floral biological and ecological characteristics, seed character detection, sowing and seedling raising experiments of
Terminalia franchetii in different seasons and container seedling cultivation results in the dry-hot valley of Jinsha river, the results indicated that the “intensively blooming pattern” of
Terminalia franchetii in the dry-hot valley is necessary for its adaptation to the dry-hot valley environment to achieve reproductive success, but it was also an important reason for its low seed plumpness and high abortion rate. The seedling establishment rate of
Terminalia franchetii in spring and autumn was 11.2% and 10.9% respectively, which were basically sufficient for productive seedlings under existing conditions. The 4-month-old seedling height of spring sowing seed seedling could reach 81.6% of the 9-month-old seedling height of autumn sown seed seedlings, which indicating that spring sowing was more suitable for productive cultivation of
Terminalia franchetii seedlings.
